Flywheel Energy Storage System

American Maglev Technology of Florida, Inc., GA, United States


AMT has developed a flywheel energy storage system that is capable of providing up to 5.5 kilowatt hours of energy storage and delivering 4 kilowatt hours at a given time. The flywheel rotor is made of carbon fibers allowing for greater energy storage per volume.

Primary Application Area: Energy Storage

Technology Development Status: Prototype

Technology Readiness Level: TRL 4


Value Proposition: Flywheel energy storage has been considered for a long time. The challenge has always been how to be cost effective. Using cost effective carbon fibers with a mass loaded flywheel design allows us to effectively increase the amount of energy storage per kilogram at an attractive cost.


Organization Type: Early-stage Startup (Seed)

Showcase Booth #: 235



Government Funding/Support to Date: Funding for this research is provided under a Phase II STTR grant through the Office of Naval Research. AMT is about to conclude the base period of the research. during the option period we are planing on building and testing to failure a couple of the composite rotor designs. These tests will be used to validate the simulation models.

AMT has begun preliminary discussions with ONR regarding Phase 2 Option 2, where we would build and test a full scale prototype. this work could also be considered for a possible Phase 3.

Primary Sources of Funding: Federal Grant

Looking for: Both Funding and Development Partners
